Red Hat Load Balancer Add-On - subscription (1 year) - 1 license

Red Hat's Network Load Balancer Add-On provides redundancy for web serving, databases, networking, and storage. By creating a virtual address that can be directed to a real server for load balancing or traffic shaping, the Red Hat Network Load Balancer Add-On allows you to quickly add or remove servers or change balancing algorithms using a browser-based graphical user interface (GUI).

The Network Load Balancer Add-On provides support for transmission control protocol (TCP) and user datagram protocol (UD P) load balancing independent of applications. It is composed of two major components: the Linux Virtual Server (LVS) and the Piranha Configuration Tool, a GUI-based management tool. The Network Load Balancer Add-On can be configured across two nodes in an active/passive configuration to provide redundant traffic management services.
